  2. Trickle charging - Wikipedia

    en.wikipedia.org/wiki/Trickle_charging

    Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.

  3. Battery charger - Wikipedia

    en.wikipedia.org/wiki/Battery_charger

    A properly designed charger can allow batteries to reach their full cycle life. Excess charging current, lengthy overcharging, or cell reversal in a multiple cell pack cause damage to cells and limit the life expectancy of a battery. Most modern cell phones, laptop and tablet computers, and most electric vehicles use lithium-ion batteries. [28]

  4. Rechargeable battery - Wikipedia

    en.wikipedia.org/wiki/Rechargeable_battery

    For example, some battery types can be safely recharged from a constant voltage source. Other types need to be charged with a regulated current source that tapers as the battery reaches fully charged voltage. Charging a battery incorrectly can damage a battery; in extreme cases, batteries can overheat, catch fire, or explosively vent their ...

  6. Failure of electronic components - Wikipedia

    en.wikipedia.org/wiki/Failure_of_electronic...

    A sudden fail-open fault can cause multiple secondary failures if it is fast and the circuit contains an inductance; this causes large voltage spikes, which may exceed 500 volts. A broken metallisation on a chip may thus cause secondary overvoltage damage. [1] Thermal runaway can cause sudden failures including melting, fire or explosions.
